Özet
Late stent thrombosis is very rare in bare metal stents. We report a 72-year-old male patient who developed late thrombosis of a bare metal stent implanted in the left main coronary artery (LMCA). The patient presented with cardiogenic shock 350 days after the first stent implantation. Coronary angiography showed total occlusion of the stent. Following the first balloon predilatation of the lesion, a flow in the LMCA was observed, but there was no flow in the left anterior descending (LAD) artery. Then, a bare metal stent was implanted into the LAD. Although the flow was maintained and all inotropic support continued, hypotension persisted. Angiography of the right coronary artery demonstrated 90% stenosis at the same location which had been observed as a noncritical lesion during the first percutaneous coronary intervention. As the patient was in shock, the right coronary artery was also stented and TIMI 3 flow was obtained. However, the patient developed cardiac arrest and died despite repeated efforts of cardiopulmonary resuscitation. It was learned that the patient had undergone an urological operation for bladder stone nine days before, for which both aspirin and clopidogrel were discontinued six days before the operation. Only aspirin was reinitiated three days after the procedure. He then presented to our hospital with cardiogenic shock on his first day after discharge.
